CHARLES B. ROZAR, F EMPIRE, GEORGIA.

HARROW.

To all whom it may concern:

Be it known that 1, CHARLES B. Home, a citizen of the United States,residing at Empire, in the county of Dodge and State of Georgia, haveinvented a new and useful Harrow, of which the following is aspecification.

The objects of the invention are, generally, the provision in amerchantable form, of a device of the above mentioned class, which willbe inexpensive to manufacture, facile in operation, and devoid ofcomplicated parts; specifically, the provision of novel means, wherebythe implement may be adjusted to sweep zones of different widths; theprovision of means whereby the space between the teeth of the harrow maybe adjusted; and the provision of means whereby the maximum and minimumpositions of the movable parts of the harrow maybe determined as theharrow is expanded or contracted, respectively; other and furtherobjects being made manifest hereinafter, as the description of theinvention progresses.

The invention consists in the novel con struction and arrangement ofparts hereinafter described, delineated in the accompanying drawings,and particularly pointed out in that portion of this instrument whereinpatentable novelty is claimed for certain distinctive features of thedevice, it being understood, that, within the scope of what hereinafterthus is claimed, divers changes in the form, proportions, size, andminor details of the structure may be made, without departing from thespirit or sacrificing any of the advantages of the invention.

Similar numerals of reference are employed to denote corresponding partsthroughout the several figures of the drawings.

In the accompanying drawings :F igure 1 is a top plan, the arms beingextended; Fig. 2 is a top plan, the arms being retracted; Fig. 3 is aside elevation, parts being broken away.

The invention includes primarily, a plow beam 1, on the under side ofwhich, at its forward end, is mounted a transversely disposed clevis 2.Mounted upon. the lower face of the beam 1, to the rear of the clevis 2is a transverse head 8. Located upon the upper face of the beam 1 invertical alinement with the clevis 2, is a transverse head 5 securelyassembled by means of bolts or the like, with the plow beam and with theSpecification of Letters Patent.

Application filed August 19, 1909.

Patented May 31, 1910.

Serial No. 513,618.

clevis Q. Mounted upon the upper face of the beam 1 to the rear of thehead 5 and in alinement with the head 3, vertically, is a transversehead 7 secured in any suitable manner to the plow beam and to the head3, preferably by means of bolts passing through the elements last abovementioned. Arms 8 extending laterally from the beam 1,- upon each sidethereof, are provided, the adjacent ends of these arms 8 being pivotallymounted between the head 5 and the clevis 2. Arms 9 disposed parallel tothe arms 8, are provided, these last named arms being pivotally mountedat their adjacent ends, between the heads 3 and 7.

The invention includes a plurality of teeth 10 disposed to the rear ofthe arms 9 and provided with extensions 11 disposed upon the upper facesof the arms 8 and 9 and pivotally connected therewith.

Slidably mounted upon the beam 1, tothe rear of the arms, and arrangedto inclose the beam 1, is a rider 16. A connecting element, a bolt orthe like, is carried by the rider 16 and arranged to upstand therefrom.This connecting element which is denoted by the numeral 80, is adaptedto register in apertures in the adjacent, overlapped ends of braces 14,the remote ends of which are pivotally mounted upon one of the memberswhereby the extensions 11 of the teeth 10 are assembled with the arms.In the present instance, the pivot bolts 12 whereby the outer of theteeth 10 are assembled with the rear arms 9, have been selected to serveas mountings for the remote ends of the braces 14, in order that thethrust whereby the arms 8 and 9 are operated, may be applied adjacentthe ends of said arms, in order that the longest possible leverage foroperating the arms 8 and 9 may be obtained.

Mounted at its forward end upon the bolt is a rearwardly extending bar17, spaced vertically at its rear end from the beam 1, and therebifurcated to form arms 18, disposed upon each side of a lever 19 andpivotally connected therewith, the lever 19 in its turn, beingbifurcated at its lower extremity to form arms 31, disposed uponopposite sides of a segment 20 and pivotally connected therewith, thesegment 20 being rigidly mounted upon the plow beam 1 adjacent the rearend thereof.

Mounted upon the rear face of the lever 19 is a bearing 22, in which isslidably mounted a pawl 21, provided at its lower extremity with a head23 adapted to engage the teeth of the segment 20. A compression a handlever 25 is pivoted to the upper extremity of the member 19 andoperatively connectedwith the upper extremity'of the" pawl 21.

Handles 26 are pivoted at their lower ends to the beam 1 adj acentetherear end thereofv and to the .intermediate' 'pontions of these handles;726 are .pivotedthe upper ends-of depending braces 27, provided attheirlower.

endswitha series of apertures 28, adapted to 1'6061V8,= successively, aconnecting element, whereby thebraces 27 may be assemm bled with the:rear endof the: beam=l, to

ing between-theteeth-10, the lever 19 may be moved, and when the desiredadjustment 1 has been secured,.the lever maybe retained in place by theengagementbetween the head 23 and the. teeth of the. segment 20. Themold boards 29 .are' adapted to con-1 tact .with the: rider l6,.therebylimit-ing the forwardsliding movement. thereof. -.The'

lowen extremities of the handles-26 are-:-

of the. rider 1 6.

Having. thus described my invention, .what; 1. I claim. as new anddesire to protect by Letters Patent is 1. A device of the classdescribed comprising a beam; arms disposed upon each spring 24 ismounted upon-thelever 1-9 between the head 23 and the bearing 22, and
